Item Details
- Honeywell UOP Molecular Sieves* are synthetically produced, crystalline metal aluminosilicates that have been activated for adsorption by removing their water of hydration. Unlike other adsorbents, Molecular Sieves have a precise uniform size and molecular dimension. 4A-AP Molecular Sieve activated powder adsorbent is the sodium form of the Type A crystal structure. An alkali metal aluminosilicate, 4A-AP adsorbs molecules with critical diameters up to 4 Angstrom. *Airgas repackages and markets Molecular Sieves manufactured by Honeywell UOP. This product is a 90 kg drum of 4A Powder that is non returnable
Features
- Nominal Pore Diameter (angstroms) - 4
- Particle Size (microns) - <10
- Bulk Density (lb/ft³) - 32
- Equilibrium H2O Capacity* - 27
- Moisture Content (wt.-%) - 1.5
- * Measured at 17.5 mm Hg and 25°C
Applications
- 4A molecular sieve powder is used in many urethane formulations and metal-rich paints/coatings are extremely susceptible to moisture contamination during production and storage.
- For urethane-based coating, adhesive, sealant, and elastomer formulations, water will react with isocyanate, which may cause product curing problems, carbon dioxide off-gassing, blistering, and degradation of other physical properties.
- For zinc or aluminum paints/coatings, water in the presence of reactive metal dust can react to generate hydrogen, greatly reducing product shelf life.
- 4A-AP molecular sieve powder is a superior water scavenger in these and many other moisture-sensitive applications.
